Manu Types Flashcards
What is the fundamental goal of a manufacturing process?
To produce a product that has a useful form.
What are the three stages in the manufacturing process?
- Change the physical properties of the raw material
- Change the shape and size of the workpiece
- Achieve the required dimensional accuracy (tolerances) and surface finish.
What is a manufacturing process?
An important step in the production process.
What is forming in manufacturing?
A mechanical process used in manufacturing industries.
What does shaping do in manufacturing?
Used to change the size and shape of a workpiece.
What is the purpose of finishing in manufacturing?
Alters the surface of a manufactured part.
What is casting?
Molten material (e.g., metal) is poured into a mould that contains a hollow cavity of the exact required shape.
What is additive manufacturing?
Creating an object by building it one layer at a time.
What is the wasting process?
Material is either cut away or drilled out/removed.
What are the categories of forming processes?
- Bulk forming
- Sheet metal forming
- Powder metal forming
What are the four categories of shaping processes?
- Casting
- Manipulative processes
- Powder techniques
- Cutting and grinding
What are the two main categories of finishing processes?
- Removing and reshaping
- Adding and altering
What are some commonly desired characteristics of finishing processes?
- Improved aesthetics
- Adhesion
- Solderability
- Chemical, corrosion, tarnish or wear-resistance
- Hardness
- Electrical conductivity
- Flaw removal
- Surface friction control
What are the two broad categories of casting processes?
- Expendable mould processes
- Permanent mould processes
What is a pattern in casting?
A replica of the object to be cast, used to prepare the cavity for molten material.
What are the types of additive manufacturing?
- Powder bed fusion
- Vat photopolymerisation
- Sheet lamination
- Directed energy deposition (DED)
- Binder jetting
- Material jetting
- Material extrusion
What is sintering?
The process of compacting and forming material by heat or pressure.
What are the five predominant joint types in joining processes?
- Butt
- Tee
- Corner
- Lap
- Edge
What tools and methods are used in the wasting process?
- Guillotining
- Drilling
- Laser cutting
- CNC routing
True or False: The casting process is always simple and requires no skill.
False.
Fill in the blank: The _______ process involves the use of molten liquid, which is poured into a mould that takes the form of the finished part.
casting
What is the significance of good design in the wasting process?
It can minimize the amount of waste produced.
What is the role of joints in assembly?
To transmit or distribute forces generated during use from one part to the other parts of the assembly.
